Stripnulls Explanation

VB Code:

Function StripNulls(OriginalStr As String) As String
If (InStr(OriginalStr, Chr(0)) > 0) Then
OriginalStr = Left(OriginalStr, InStr(OriginalStr, Chr(0)) - 1)
End If
StripNulls = OriginalStr
End Function

Ok, I know what that does, but I'm not so familiar with string functions, so... how does it work... and why do I get nulls from c++ but I can't add nulls to a string? like:

VB Code:

for I = 0 to 10
stringname = stringname & null (or vbNull?)
next i

adding vbNull to the end of the string should add a null character to it. If it doesn't work, you can always use Chr(0), which is the ASCII for null. That StripNulls function looks like it is cutting off the whole string after the first null it incounters.

if the stringname is a string datatype how will it help u cannot add null to string variables.

if u need blank spaces u can use " " or space() function

No, I was just trying that to see if a function worked, but it seemed to never add the nulls, and I was wondering why VB (if it won't let me add nulls) was just cutting them of, in which case why it wouldn't do it when returned from a API.

Thank you both!

vbNull <> vbNullString

use VBNULLSTRING instead of VBNULL
